Google Demand Gen: Visuals Win in 2026

For Google Demand Gen campaigns in 2026, it’s all about the visuals. If you’re trying to capture someone’s fractured attention with text alone while they’re scrolling through their feeds, you’ve already lost. Striking images and good video are what drive engagement and conversions now. They’re not just nice-to-haves. The real question is how you can produce visuals that consistently get results without just adding to the noise.

Setting Up Your Google Demand Gen Campaign for Visual Success

A Google Demand Gen campaign is built to put your visual stories right where people are already watching and scrolling on YouTube, Discover, and Gmail. This means the quality of your visuals isn’t just important, it’s everything. Getting the setup right in the Google Ads interface is the first, non-negotiable step.

Accessing Demand Gen Campaigns

1. Log into your Google Ads account. Find and click Campaigns on the left-hand navigation menu.

2. Hit that big blue + New Campaign button to get the whole process started.

3. Google will ask for a campaign objective. Pick something like Sales, Leads, or Website traffic, since those fit what Demand Gen is supposed to do. After you pick one, a list of campaign types appears. You’re looking for Demand Gen, which is usually sitting there next to “Search,” “Display,” and “Video.”

4. Next up is selecting conversion goals. Google will suggest some based on your account history, but you should click Choose conversion goals for this campaign to add or remove actions yourself. This makes sure you’re tracking the right stuff from day one. I’ve seen too many marketers skip this and then wonder why their reporting is a mess weeks down the line.

Pro Tip: Before you go any further, double-check that your Google Analytics 4 (GA4) property is properly linked to Google Ads. Demand Gen relies heavily on audience signals and good conversion data, and GA4 is where the strongest data comes from for optimization. There’s a Google support document that walks you through the linking process.

Crafting High-Impact Image Assets

Good images are fundamental to a Demand Gen campaign. They need to look good, match your brand, and be ready for all the different places they’ll show up. Don’t just think about one perfect “hero” image. A diverse set of assets is required to get the best reach and engagement.

Image Specifications and Upload

1. Inside your campaign setup, go to the Ads & assets section. This is where you’ll put your ad creative together.

2. Click New Ad, then pick Demand Gen ad to open up the main ad creation screen.

3. Find the Images area and click the + button. Google wants at least five unique images for every ad group. To give the algorithm the best chance, you should provide a mix of aspect ratios, specifically:

   • Field (1.91:1): Use 1200×628 pixels. These look great in Discover feed placements.
   • Square (1:1): Use 1200×1200 pixels. These work well for YouTube in-stream ads and in Gmail.
   • Portrait (4:5): Use 960×1200 pixels. This is your go-to for mobile-first views.

   Make sure every image is high-resolution (the minimums are 600×314 for field, 300×300 for square, and so on) and keep the file size under 5MB. The system will try to crop and resize for you, but starting with the right ratios prevents your images from getting butchered.

4. Now, upload your images. You have a few options: pull from your Asset Library, upload from your machine, or scan a website. I’d recommend getting in the habit of using the Asset Library. It keeps all your approved creative in one place.

5. For every image, Google will ask you to confirm the aspect ratio and might suggest a crop. Pay attention here. A Statista report on social media usage shows just how much visual content people see daily, so your image needs to grab them instantly.

Common Mistake: Don’t use low-res images or pictures with a bunch of text slapped on top. Google’s system can penalize ads that look like spam or are hard to read on a phone. If text is absolutely necessary, keep it short and use high-contrast fonts.

Integrating Dynamic Video Content

People are watching more video than ever, and Demand Gen campaigns are built to take advantage of this by putting videos on YouTube and other placements. A good video can create a much deeper connection than a static image by showing a product in action or telling a quick story.

Video Asset Selection and Specifications

1. Back in the Ads & assets section, find the Videos subsection and click the + button.

2. You’ll add videos by linking them from YouTube, which means you have to upload them to a YouTube channel first. You can find them with a URL or by searching the channel name. The goal is to have at least two or three different videos in each ad group.

3. Here are the key video specs to remember:

   • Length: Google accepts videos from 15 seconds up to 3 minutes, but for generating demand, shorter videos in the 15-30 second range almost always perform better. You have to get their attention fast.
   • Resolution: Use 1080p (Full HD) as your minimum. A higher resolution always helps, especially if it’s viewed on a big screen.
   • Aspect Ratios: The standard 16:9 (field) is your main format, but you should also have a 9:16 (portrait) version for YouTube Shorts and a 1:1 (square) one for general compatibility.
   • File Size: The technical limit is 256 GB, but any normal marketing video will be way, way smaller than that.

4. Once you select your videos, Google Ads shows you a preview. This is your last chance to check that it looks right and gets the message across. I’ve found that videos with a clear call-to-action within the first 5 seconds do way better than ones that save it for the end. Viewers just aren’t that patient. They will scroll.

Expected Outcome: Solid video production leads to better engagement rates and, according to HubSpot’s marketing statistics, can drive more conversions than other types of content. It’s all about getting someone to take a tangible action, not just watch a video.

Writing Compelling Ad Copy and Calls-to-Action

The visuals get the attention, but it’s the words that get the conversion. Your headlines and descriptions have to support your images, telling a quick story that funnels the user to whatever action you want them to take.

Headline and Description Best Practices

1. In the ad creation screen, scroll down to Headlines and Descriptions. You’re required to give Google multiple options for its machine learning to work with.

   • Headlines: Write at least five unique headlines, keeping them under 30 characters. They should be catchy and benefit-focused, and they need to make sense with the visuals. Try mixing some product-centric headlines with others that focus on solving a problem.
   • Long Headlines: You also need at least one long headline, up to 90 characters. This gives you space for a bit more detail and often shows up in Discover feeds.
   • Descriptions: Provide at least three unique descriptions, up to 90 characters each. Use this space to add detail to your headline’s promise or to call out a unique selling point.

2. Be clear and concise. No jargon. People are scanning, so your copy has to be understood in a split second. A classic mistake is trying to jam too much information into one headline. Short and punchy often works better.

3. Make sure the tone of your copy matches the visuals. If the image is calm and serene, aggressive sales copy is going to feel weird and kill trust. That mismatch is a recipe for low engagement.

Call-to-Action (CTA) Selection

1. Just below the description fields is the Call to action dropdown. Google provides a list of standard CTAs like Shop now, Learn more, Sign up, Apply now, and Book now.

2. Pick the CTA that literally describes what you want the user to do next. If the ad clicks through to a product page, “Shop now” is the right choice. If it goes to a blog post, “Learn more” is better. A mismatched CTA is a great way to get a high bounce rate because the user feels tricked.

3. There’s also an Automated option, where you let Google’s algorithm pick the CTA. It can work, but I usually prefer to set it myself so I have more control over the user’s path.

Pro Tip: If it makes sense for what you’re selling, think about using Dynamic Keyword Insertion (DKI) in your headlines. It can make the ad feel more personalized, but you have to manage it carefully to avoid looking foolish with weird, irrelevant insertions.

Audience Targeting and Bid Strategy for Visual Campaigns

The best visuals in the world won’t do you any good if the wrong people see them. Strong visuals succeed with the right audience, and Demand Gen campaigns have excellent targeting options to make sure your ads find the people most likely to convert.

Defining Your Audience

1. In the campaign setup, you’ll find the Audiences section. This is where you tell Google who should see your ads.

2. I always start with Custom Segments. This lets you build an audience based on Google search terms, websites they’ve visited, or even apps they’ve used. For example, if you sell high-end coffee beans, you could target people who search for “best pour-over coffee makers” or who read specific coffee blogs.

3. Then, layer in Your data segments, which is just Google’s new name for remarketing lists. This is your chance to show amazing product shots to someone who just abandoned a cart on your site, which is an incredibly effective tactic.

4. You can also explore Interests & detailed demographics. Google groups people into broad interest categories like “Food & Dining” or “Travel.” You can layer these to narrow your audience, but don’t get so specific that you choke off all your reach.

5. For Demand Gen, you absolutely should be using Lookalike segments. These target new users who behave like your best existing customers. If you have solid first-party data (like a list of high-value purchasers), this is a powerful way to expand your reach because Google’s algorithm is great at finding similar users across its network.

Editorial Aside: Don’t treat Demand Gen like a “spray and pray” firehose. The reach is huge, but you still need precise targeting. A well-defined audience seeing a relevant, visually rich ad will always outperform a generic ad sent to everyone. It’s all about relevance.

Selecting a Bid Strategy

1. Under the Bidding section, you have a few choices. For Demand Gen, the common strategies are:

   • Maximize conversions: This tells Google to get you the most conversions possible within your budget. It’s a good place to start, assuming you have enough conversion data for the algorithm to learn from.
   • Target CPA (Cost Per Acquisition): You give Google a target CPA, and it tries to hit that average. You need to know what a new customer is worth to you for this to work.
   • Maximize conversion value: This is the right choice if your conversions have different values, like if you’re selling both a $10 product and a $500 one. It optimizes for total revenue, not just the number of sales.

2. Finally, set your budget. This is the average you want to spend per day. Keep in mind that Google can spend up to double your daily budget on a good day, but it will never go over your total monthly spend (which is just your daily budget multiplied by 30.4).

Expected Outcome: When you combine a smart bid strategy with sharp audience targeting, you ensure your great-looking ads are actually shown to people who will engage and convert. This is how you get a good return on ad spend. Without that strategy, your beautiful visuals are just expensive art.

Monitoring and Optimizing Visual Performance

Getting the campaign live is step one. Now the real work begins. You have to constantly monitor and optimize your visual assets if you want any kind of long-term success, using data to make sure your campaigns stay efficient.

Analyzing Asset Reports

1. Once your campaign has been running for a bit, go back to the Ads & assets section and click on Assets.

2. This report gives you a full breakdown of how every single image, video, and piece of copy is performing. You’re looking for metrics like Impressions, Clicks, CTR (Click-Through Rate), and Conversions.

3. The most important column here is Performance. Google will label your assets as “Learning,” “Low,” “Good,” or “Best.” Anything labeled “Low” is underperforming and you should think about swapping it out. The “Best” assets are your winners and should be the model for your next round of creative.

4. Use the filters to look at asset types individually. You might find that your square images are getting a much higher CTR on YouTube, while the 1.91:1 field images are doing all the work on Discover. This is the kind of insight you need to act on.

A/B Testing and Iteration

1. Use your asset reports to find the losers. Then, create new versions that try to fix what was wrong. For images, maybe that means trying a different color palette, using a different model, or showing the product from another angle. For videos, you could test a shorter cut, a different opening hook, or a more direct CTA.

2. Upload the new assets into your existing ad groups. Google’s system will automatically start testing them against the old ones. The key is to be patient and let the new assets get enough data (I usually wait at least two weeks or for about 5,000 impressions per asset) before you decide if they’re a success or failure.

3. Be ruthless about cutting what’s not working. If an asset is consistently performing poorly, get rid of it. It’s just wasting your budget and dragging down the whole campaign. It doesn’t matter how much time you spent making it.

4. Keep your creative fresh. People get tired of seeing the same ads over and over again, a problem we call visual fatigue. For any campaign that’s running for a while, you should be introducing new visual concepts every 4 to 6 weeks to keep engagement from dropping off.

This cycle of testing, analyzing, and refining your visuals is what makes a Demand Gen campaign go from good to great. It isn’t a “set it and forget it” platform. It requires a constant effort to figure out what your audience actually wants to see.

To get Google Demand Gen visuals right, you have to be disciplined about delivering content that stops the scroll and pushes for an action. From the first setup screen to the ongoing optimization reports, it’s all about a strategic approach to your images, videos, and copy. The point isn’t just getting seen, it’s getting a click and a conversion in a crowded digital feed.
